Specification forming part of Letters Patent No. 170,680, dated December7, 1875; application filed August 25, 1875.

To all whom it may concern:

Be it known that I, WILLIAM MOBARNARD, of Clarksville, in the county ofButler and State of Iowa, have invented an Improved Pump, of which thefollowing is a specification:

My invention is a pump specially adapted to elevate water from a well ina continuous forced stream by rotating a shaft. It consists in arrangingand combining a reservoir, a series 0f cylinders and pistons, areceivingchamber, a wellltube and air-chamber, and a rotating shaftcarrying a grooved cam, as hereinafter fully set forth.

My drawing is a perspective view, illustrating the construction andoperation of my invention.

A represents a metal reservoir, the basepiece ot' my complete pump. B isan induction port or tube at the center and bottom of the reservoir A. O(l is my receiving-chamber, corresponding in form and size with thereservoir A. Nos. l 2 3 represent a series of independent pump-cylindersmade of metal,

-Wood, glass, earthenware, or any suitable material. They are :fittedand fixed between the reservoir A and the receiving-chamber C, Which tWoparts are rigidly connected by means of suitable rods or screwboltsbeing passed through the flanges. These cylinders connect the twowater-chambers A and C, and the pistons operating in the cylinders liftthe Water from the reservoir to the receiving-chamber, hand from thenceforce it up through a Wel1tnbe.

D represents the cover or platform of the Well. E is a well-tube rigidlyattached to the top and center of the receiving-chamber (J. It passes upthrough the well-cover D sufciently high to discharge the water in themanner of a common pump, and to support a driving mechanism. The tube issecured to the platform or cover D in any suitable Way. a, a is arotating shaft passed through a suitable stufting-box at the l[op of thetube E, and then down through the tube and the receiving-chamber C,where it rests in a bearing in the center of the base-plate of thechamber C. b c are common bevel-gear wheels supported in a suitablebearer, d, rigidly at c is rigidly fixed to the top of the shaft a a. gis a grooved cam-wheel rigidly fixed to the shaft a, and in a centralposition in the receiving-chamber C. It stands at an angle relative toits shaft, and its inclined groove may be termed a double inclinedplane. m m represent studs or anti-friction rollers in the groove of thecam g. They are rigidly connected with the piston-rods n, which carrythe pistons up and down in the cylinders l 2 3. The pistons havesuitable valves for the passage of water, and are directed in suitablegrooves or guides r, attached inside of the Wall of the chamber C.

In the practical operation of my pump the bevel-gear Wheel b may beturned right or left by a crank, a pulley, or drive-wheel on the sameshaft, operated by hand or any suitable power to rotate the mating wheelc and the shaft a. The grooved cam-wheel g, rotating With the shaft a,Will alternately raise and lower the anti-friction rolllers m, andthereby, through the connected piston-rods it, impart a reciprocatingmotion to the pistons in the series of pump-cylinders 1 2 3. The pistonswill be thus actuated independently and successively to elevate Waterfrom the reservoir A to the receiving-chamber C, and their concertedaction will force a continuous stream upward through the tube E to bedischarged therefrom by means of a colnmon spout, s. That portionof thetube E above the spout s, closed air-tight at its top by means of thestuft'- ing-box, through which the shaft ot passes, be-

comes an air-chamber to aid the pistons in forcing the water from theWelltube, and. makes the tube E a combined Well-tube and air-chamber.Suitable hose may be attached to the spout s, for throwing the Waterwhen desired.

I am aware that a series of cylinders and 'pistons have been used topump a continuous stream, and that a cam-wheel having an inclined groovehas been used to actuate the pistons in succession to force the Watersuccessively through the same num ber of connect ed cylinders in acontinuous stream.

I am also aware that in a double-acting pump, wherein two pistons areactuated by an oscillating arm, a reservoir, two cylinders, a

tached to the top of the tube E. The Wheel receiving-chamber, and acombined waterf; wessi) j tube and air-chamber arecenneeted to'lift andA, the-series of cylinders and-y pistons 1 `2 3,

force Water. But l claim that my combinay"the reeeiving-chamber C,thecombined welltion7 wherein a rotatin g shaft passes through tube aridair-ehamberE, and the rotating shaft the entire length of the well-tubeand air. a, carrying the grooved cam g,substantially as chamber,v is newand greatly advantageous, in and for the purposes shown and described.

that it forms a pump equally well adapted -folj vWILLIAM MCBARNARD.shallow and deep Wells. "Witnesses: p
